COOLING APPARATUS.

Specification of Letters Patent.

Patented Apr. 4:, 1911.

Application filed September 24, 1910. Serial No. 583,621.

To all whom it may concern:

Be it known that I, MARY L. S'rEnN, a citizen of the United States, residin' at Elmo, in the county of Kaufman and tate of Texas, have invented certain new and useful Improvements in Cooling Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention is an improved refrigerating apparatus, especially adapted to use for cooling milk, melons, or other articles of food, the object of the invention being to provide an improved device of this character, which is simple, cheap and durable and which utilizes the evaporation of water to keep its contents cool.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :-Figure 1 is partly a side elevation and partly a vertical central sectional view of a refrigerating device constructed in accordance with my invention; and Fig. 2 is a horizontal sectional view of the same on the plane indicated bythe line a-a of Fig. 1.

In accordance with my invention I provide an upper tray 1 and a lower tray 2, the former somewhat smaller than the latter, and these are connected together by upwardly projecting supporting legs 3 which in practice may be made of sheet metal or of any other suitable material, the trays being also made of sheet metal and preferably galvanized so as to prevent them from rusting. The upper tray is provided with a central openin 4: around which is an upwardly extending flange or wall 5 and over the said opening and connected to the said flange or wall 5 is a screen 6 which in practice may be made of wire mesh or other suitable foraminous material. The lower tray 2 is provided with a discharge opening 7 from which in practice a spout or pipe 8 may lead. At points between the lower and upper trays are shelves 9 of which any suitable number may be employed and which may be arranged at any desired or suitable distance apart. These shelves are preferably made of sheet metal, but may be made of any other suitable material, and are here shown as supported on crossed braces 10, which connect the supporting legs and are provided with downturned ends 11 secured thereto.

A suitable water supply vessel 12 is disposed on the central portion of the upper tray, and is provided at its lower side with supporting legs 13 which bear on the sald tray at points around the inner flange or wall 5. This vessel 12, which in practice is filled with water, is provided with a faucet 14 which should be open to a sufficient extent to cause the upper tray to be filled with water and to slowly overflow. A curtain 15 which is preferably made of muslin but may be made of any other suitable material has its upper end secured over the outer wall or flange 16 of the upper tray 1 and the said curtain entirely covers the refrigerating device and has its lower portion disposed in the bottom tray 2. The water which overflows the upper tray saturates the curtain and evaporates and such evaporation lowers the temperature within the curtain and this is also facilitated by the central opening 4: in the upper tray which permits heated air to readily escape.

A central brace 17 extends vertically through the device and comprises sections 18. The upper section 18 is here shown as flexibly connected to the upper tray 1 as at 19 and is formed with a hook 20 at its lower end to engage an eye 21 in the center of the upper shelf 9. Each other section of the said center brace is similarly connected to one of the shelves and adapted to engage an eye in the next lower shelf. The said brace supports the central portions of the shelves and strengthens the same so as to enable them to readily withstand the Weight of the articles placed thereon and moreover the said brace by reason of its sectional con struction enables any one of the shelves to be removed without disturbing the others.

While I have herein shown and described the preferred embodiment of my invention I would have it understood that I am not limited to the precise construction and arrangement of devices herein shown and described as it is understood that minor changes may be made and other modifications within the scope of the appended claim.

Having thus described the invention what is claimed. is:

The herein described cooling apparatus In testimony whereof I hereunto affix my slgnatu-re 1n the presence of two wltnesses.
